[DhtmlXQ_comment1]平炮防卒是必然[/DhtmlXQ_comment1][DhtmlXQ_comment3]注意此时炮七进一,而不是炮七进二或进三,这是有意图的[/DhtmlXQ_comment3][DhtmlXQ_comment2_3]此种情况走炮七进二也是有意图的[/DhtmlXQ_comment2_3][DhtmlXQ_comment2_15]通过献卒,再平炮打死卒,红方形成必胜[/DhtmlXQ_comment2_15]
[/DhtmlXQ]
此局看起来简单,但其中有一点需要特别强调:如下图

假如红方进炮不到位形成如下局面,红方就不可胜,而且会输棋,为什么呢?
很显然,如果上图中轮到红方走,红方只能走炮,则卒2平3胜,如果轮到黑方走,只能走卒2平1,则兵七平六,将4进1,炮七平一,如此红方胜利,也就是:谁先走谁负。
那么我们在前期计算时,就需要将这个结果考虑进去,采用一步分成两步的方法,交出先手。
